According to the invention there is provided a method for characterizing an electrical connection between an energy storage device of an electrical or hybrid vehicle and an external power supply, the method comprising the steps of: in the vehicle, receiving an alternating waveform from the power supply; determining a fundamental frequency of the waveform; determining if the waveform is distorted; and if it is determined that the waveform is distorted, determining if the distortion is an indication of a loose connection between the vehicle and the power supply. There is further provided a charging system for characterizing an electrical connection between an energy storage device of an electrical or hybrid vehicle and an external power supply.
